MACHINE FOR MAKING CARD-CLOTHING.

SPECIFICATION forming part of Letters Patent No. 364,816, dated `Tune 14,1887. Application filed January 27, 1887. Serial No. 215,648. (No model.) Patented in Belgium September 15, 1886, No. 74,548.

To aZZ whom t may concern:

Be it known that I, ERNST GEssNER, of Aue,V Saxony, Germany, have invented a new and useful Improvement in Machines for Making Card-Clothing, specification.

The narrow bands of cardclothing produced by cardsetting machines ordinarily are provided with teeth set in rows at right angles to the length of theband, their braces or elbows being bent inA the direction of the length of the band. Whenthese bands of card-clothing are fixed on rollers and wound up in a helical line, the rows of teeth are not parallel to the axis ol' said roller, and the elbows of the teeth are not radial to said axis. This oblique position of the cards on the rollers is of disad vantage to the working effect and resistance of the teeth. The said disadvantage is removed by setting the rows of teeth in an oblique angle to the length of the band, and by bending the elbows ofthe teeth in aright angle to the rows, the degree' of the said oblique angle bearinga definite proportion to the width of the band and to the diameter of the roller onto which the band is to be fixed, so that the rows of teeth stand parallel to the axis of the roller, and the elbows of the teeth stand in radial position to said axis. Y

My invention consists in an improved machine for setting the card-teeth in rows which are arranged obliquely to the length ofthe band.

In the accompanying drawings isshown my improved machine, in which Figure 1 shows an end view. Figs. 2 and 4 are side views, showing different positions of the band; Fig. 3, a plan view of the machine, and Fig. 5 a detail of a roller covered with a band of card-clothing.

Figs. 2 and 4 show the band set with rows of teeth ha, Fig. 2 showing the rows set at right angles, as at d, and Fig. 4 in-an oblique angle, as at B.

The band A is fed forward by one of the pair of fluted rollersB. R, to which motion is imparted from a ratchet-wheel, S, already existing incommon card-setting machines, by double universal joints K K. The two fiuted rollers R R are mounted on a plate, P, movable on a pivot, B, so that by the plate P the of which the following is a rollers R R can be put in an oblique position of any required degree. The screw s and the clamp s serve for fixing the plate P in the required position.

1n altering the position of the plate P the length of the shaft L must be altered at the saine time. For this purpose the said shaft is divided into two splice-sections connected by a coupling-box, M. Instead of using the double 6o universal joints K K, motion might as well be imparted to the fluted roller R by such other mechanical means as balland-socket joints, or by bevel-wheels, Sie., or directly from the ratchet-wheel S.

The Hut-ed rollers R. R might as well be mounted in a fixed oblique position, without being adjustable, for setting the rows of teeth only at a certain angle. The feed of the band in oblique direction might as well be effected 7c by other means instead of using the iiuted rollers R R.

Fig. 5 shows a band fixed on a roller, with two rows of teeth. One of them represents a row set in the ordinary way in a right angle to the length of the band. (See angle d, Figs.

2 and 5.) rlhe said row of teeth is not parallel to the axis when laid on the roller, but forms 'a line in the direction of the arrow c, the elbows of the teeth being bent in the direction 8o of the arrow d.

The other row is set in the new way, in an oblique angle to the length of the band, see angle B at Figs. 4 and 5,) the Obliquity being in proportion to the diameter of the roller and the width of the band, forming a line in the direction of the arrow a, Fig. 5, parallelv to the axis g 7i, the elbows of the teeth being bent radially to the axis in the direction of the arrow b. 9o

The means for setting the teeth in the band is that ordinarily used, and need not be spe cially described.

IHaving thus described my invention, what I claim as new is- 1. In a machine for setting the teeth of cardclothing, the combination, with the actuating mechanism, of a pair of feed-rolls for the band set obliquely with reference to the rows of cardteeth, as and for the purpose described.

2. In a machine for setting the teeth of card.- clothing, the combination, with the actuating IOC) mechanism, of a pair of feed-rolls, and a pivthe driving-gear to one of the rolls, the said oted frame or plate carrying the feed-rolls for shaft having two universal joints in its length lo changing the angle of feed, substantially as and and being made also adjustable in its length,
